Add basic, minimal DT files for the Amlogic GXBB-based P200
development board and Hardkernel ODROID-C2 boards.

Used the other gxbb boards from Andreas Färber as a starting point.

Please keep the list sorted alphabetically. (vega-s95 only deviates in
keeping Pro and Meta sorted in logically ascending order.)

Hm, intuitively I would've named it meson-gxbb-odroid-c2.dtb. But I see
that all other *odroid*.dts are named this way, so best to stick to the
scheme I guess.

This should be "hardkernel,odroid-c2", "amlogic,meson-gxbb".

And the compatible string needs to be documented in
Documentation/devicetree/bindings/arm/amlogic.txt. Officially that's
requested to be a separate patch, so maybe split P200 and C2 while at it
to encourage people providing a Tested-by for this more common one?

Otherwise looks good and I tested a similar dtb (telos) okay on the
ODROID-C2.

How unique is P200? I wonder whether we could simplify this to
"amlogic,p200", "amlogic,meson-gxbb". I.e., is there or might there be a
P200 board for a different SoC?

Otherwise looks fine.

I think that we can safely just use "amlogic,p200" here.

Thank you!

Yeah, I would've preferred odroid-c2 as well, but decided to stick to
the pattern already set.
